Charlie discusses the Moral Orel episode he is an uncredited writer on.
Also, great brief interview concerning Charlie & Duke Johnson's Anomalisa.

That's exactly what I was looking for. Thank you!

Yep. Charlie gave Dino an idea for an episode:
Dino S.:
Charlie Kaufman actually had a great idea for one [episode] but he's very busy. I might write it and bounce it off him a little bit. [The idea] was based on his wife buying a horse from this woman. This woman sold it to Charlie's wife only because she started loving the horse more than Jesus. I wanted to do a show where Orel has a pet of some kind because I wanted to bring his mother into the whole episode. I have this idea that his mother hates animals and wants them around only for eating. So I always liked the idea of Orel owning a dog. Right now it is still a germ but it's going to be about Orel having this puppy that he loves more than Jesus and what he goes through because of that. (

and it did indeed become an episode of the show, called "Love":
Orel became a great series in its second & third seasons (before being cancelled by Adult Swim for having too much pathos & not enough pee jokes) I'd strongly recommend seeking out the second & third seasons if you can find them - I think you can view the episode Love on the Adult Swim website or on the second disc of Moral Orel - Volume 1.
